BACKGROUND The impact of body mass index (BMI) on laparoscopic surgery for colorectal cancer in Asian countries is unclear, partly because obesity is less common in Asia than in western countries. The purpose of this study was to evaluate the association between BMI and short-term outcomes after laparoscopic resection for colorectal cancer in Japanese(More)
BACKGROUND Although the laparoscopic approach is accepted for the treatment of colon cancer, its value for low rectal cancer is unknown. The purpose of this study was to evaluate the influence of patient and tumor factors, particularly pelvic dimensions, on the difficulties in laparoscopic total mesorectal excision (TME) for low rectal cancer. METHODS(More)
BACKGROUND Laparoscopic rectal cancer surgery involving rectal division with intracorporeal stapling devices is technically difficult. This study aimed to identify risk factors for anastomotic leakage associated with laparoscopic anterior resection for rectal cancer. METHODS We studied 363 patients who underwent laparoscopic anterior resection with(More)
BACKGROUND The role of laparoscopic surgery for transverse colon cancer (TCC) remains controversial. This study aimed to evaluate the safety of laparoscopic resection of TCC. METHODS Fifty-three patients undergoing laparoscopic resection of TCC (group A) were compared with 39 patients undergoing open resection of TCC (group B) and 200 patients undergoing(More)
PURPOSE The role of laparoscopic resection in management of rectal cancer is still controversial. The purpose of this study was to evaluate whether laparoscopic rectal resection for rectal cancer could be safely performed in elderly patients. METHODS Forty-four elderly patients (> or =75 years) undergoing laparoscopic rectal resection (group A) were(More)
BACKGROUND Laparoscopic surgery for colon cancer in the splenic flexure (SF cancer) is technically demanding and has not been evaluated in randomized clinical trials. This study aimed to evaluate the safety and feasibility of laparoscopic surgery for SF cancer. METHODS Thirty-three patients undergoing laparoscopic surgery for SF cancer (LAC group) were(More)
BACKGROUND Rectal transection and anastomosis at the lower rectum is the most challenging part of laparoscopic low anterior resection. Therefore, some have demonstrated that rectal transection should be performed using instruments for open surgery with small laparotomy. In our institute, however, rectal transection using a currently available endostapler(More)
BACKGROUND Lateral lymph node (LLN) dissection contributes to a decrease in local recurrence and prolongs survival in locally advanced lower rectal cancer patients as compared with total mesorectal excision (TME) alone [1, 2]. However, this procedure is also accompanied by increased bleeding and postoperative complications [3, 4]. Recently, laparoscopic TME(More)
BACKGROUND The significance of lateral pelvic lymph node (LPLN) metastasis in advanced low rectal cancer treated with preoperative chemoradiotherapy (CRT) remains unclear. The objective of this study was to evaluate the outcomes of selective LPLN dissection (LPLD) based on the pretreatment imaging in patients with advanced low rectal cancer treated with(More)
BACKGROUND Loop ileostomy is customary after very low rectal anastomosis to reduce the rate of pelvic sepsis that can result from anastomotic leakage. To evaluate complications of stoma closure is important to maximize the benefit of making the defunctioning stoma. The aim of this study was to examine possible risk factors associated with complications,(More)
